粘贴下列代码到 Edit1.click 事件中，运行时可以看到点击位置的字符和坐标位置（相对于表单客户区原点）
只要明白了 GetCaretPos 的作用，取第二个“节”字的坐标也就易如反掌

程序代码：

Declare Long GetCaretPos in win32api String @

pt = BinToC(0,'rs') + BinToC(0,'rs')
GetCaretPos(@ pt)
x = CToBin(Substr(pt,1,4), 'rs')
y = CToBin(Substr(pt,5,4), 'rs')

cc = Substr(This.Text, This.SelStart+1, 1)
Do case
Case IsLeadByte(cc)
    cc = ["] + Substr(This.Text, This.SelStart+1, 2) + ["]
Case Asc(cc) < 33
    cc = Textmerge('CHR(<<Asc(cc)>>)')
Otherwise
    cc = ["] + cc + ["]
EndCase
cc = Textmerge('char=<<cc>>，x=<<x>>，y=<<y>>')
Wait windows cc nowait noclear

这家伙很懒，啥也没留下

谢谢老师，这个太好了！

再次请教csyx老师，如何把这段代码修改成：把编辑框的内容从头到尾把所有'_'的x,y坐标保存到表中？谢谢，辛苦了！
